Cold Air Intake and Exhaust tips for 305 vortec

Just wondering everyone's opinion on cold air intakes and exhaust systems. I have a 1997 chevy c1500 silverado 2WD with a 5.0L vortec V8. I want to do some performance customization and I need to know good brands and ideas regarding exhaust systems and cold air intakes. I have a limited budget, so cheap (yet still quality) is good. thanks all!
